( Figs. 41 , 221–222 , 397 , Map 46)

Diagnosis.— Hypatopa umbra is similar to H. texo in facies but differs from the latter by having a narrower base of the uncus; a more constricted base to a downcurved proximal flange of the dorsal part of the valva; a broader phallus; and a more broadly curved sclerite of the phallus. H. umbra also has a slightly protuberant median lobe of the ventroposterior margin of the gnathos; sockets of tergal setae not extending beyond the midlength of the tegumen; a straight apical process of the ventral part of valva; an inwardly curved digitate process of the dorsal part of the valva; and an anellus that is setose on the basal 1/2 that are lacking in H. texo .

Description.—Head: Vertex and frontoclypeus grayish brown. Outer surface of labial palpus brown intermixed with pale-brown scales along apical margin of segment 2, inner surface pale brown. Antennal scape pale brown, pecten pale brown, flagellum brownish gray. Proboscis pale brown.

MAP 46. Distribution of Hypatopa umbra (●) and H. texo (˔).

Thorax: Tegula and mesonotum grayish brown. Legs brown intermixed with pale-brown scales near midsegments and apical margins of all segments and tarsomeres. Forewing ( Fig. 397 ): Length 3.5–5.1 mm (n = 15), pale brown intermixed with brown scales; base brown, gradually brightening to 1/3; cell with two spots on apical end along crossvein, anterior spot small, posterior spot larger, expanded into tornal area; marginal spots dark brown. Undersurface brown. Venation ( Fig. 41 ) with M3 and CuA1 arising from a common point on distoposterior part of cell; cubital veins divergent from bases with CuA1 straight and CuA2 broadly curved basally. Hindwing: Translucent pale brown gradually darkening to apex. Venation ( Fig. 41 ) with cubitus 3-branched; M2+M3 arising from cubitus beyond distoposterior part of cell.

Abdomen: Male genitalia ( Figs. 221–222 ): Uncus gradually narrowed from base, acutely downcurved apically, sparsely setose, shorter than width of anal opening. Gnathos, narrow band, confluent with tegumen; ventroposterior margin slightly protuberant mesially, forming emarginate, median lobe. Sockets of tergal setae not extending beyond midlength of tegumen. Valva divided; ventral part angular basally, widening to near middle, gradually narrowing to base of large apical process; process straight throughout most of length, acutely curved apically, setose on outer surface, planate on inner surface; ventral margin sparsely setose, upturned beyond middle, forming wide fold to near base of setose marginal ridge at base of apical process; dorsal part with apical portion of costa extending dorsally, forming setose digitate process; process broadly curved inwardly; basal ridge of digitate process extending ventrally fusing with dorsolateral ridge of proximal flange; flange subcircular beyond protracted base, with a broadly rounded apical margin, spiculate, setose along apical margin; margin shallowly serrate. Juxta bandlike. Vinculum semicircular. Phallus and sclerite of phallus shorter than valva, broadly curved near 2/3; anellus narrowed from widened base, narrowly rounded apically, setose on basal 1/2. Female Genitalia: Unknown.

Distribution (Map 46). Hypatopa umbra is known from two collecting sites; one on the western most part of the Cordillera de Guanacaste, and one on the Cordillera de Tilarán in western Costa Rica.

Etymology. The specific epithet umbra is derived from the Latin meaning, shadow.
